Line a baking sheet or jelly roll pan with parchment or Silpat. Set aside.
Prepare the apples by washing and drying them, making sure to remove any wax that may prevent the candy coating from sticking. Insert the sticks at this time as well.
Combine the granulated sugar, water & corn syrup in a 2-qt saucepan. Bring to a boil stirring constantly.
Continue to boil until you reach 300 degrees- hard crack temp.
Remove from heat & quickly AND CAREFULLY add in the food coloring & candy flavor. USE CAUTION to not breathe in the steam when adding the flavor oil as the oil droplets in the steam can be harmful to the lungs. Stir.
Immediately start dipping & rolling the apples in the liquid candy. You may need to tilt the pan slightly to cover the apples depending on their size.
I did one coat & then placed them on the parchment. Once they were all coated I drizzled out the remaining candy in the pan over the top of the apples to give an extra coat.
Sprinkle with any decorations desired at this time. Allow the apples to sit at room temperature to harden.
Store in an airtight container or wrap them with plastic wrap.
